Note: Error LEDs remain lit only while the server is connected to power.
Installation guidelines
Use the installation guidelines to install the System x3650 M3 Types 4255, 7945,
and 7949
Attention: Static electricity that is released to internal server components when
the server is powered-on might cause the system to halt, which might result in the
loss of data. To avoid this potential problem, always use an electrostatic-discharge
wrist strap or other grounding system when removing or installing a hot-swap
device.
Before you install optional devices, read the following information:
v Read the safety information that begins on page “Safety” on page v, the
guidelines in “Working inside the server with the power on” on page 39, and
“Handling static-sensitive devices” on page 40. This information will help you
work safely.
v When you install your new server, take the opportunity to download and apply
the most recent firmware updates. This step will help to ensure that any known
issues are addressed and that your server is ready to function at maximum
levels of performance. To download firmware updates for your server, complete
the following steps:
1. Go to http://www.ibm.com/systems/support/.
2. Under Product support, click System x.
3. Under Popular links, click Software and device drivers.
4. Click System x3650 M3 to display the matrix of downloadable files for the
server.
For additional information about tools for updating, managing, and deploying
firmware, see the System x and xSeries Tools Center at http://
publib.boulder.ibm.com/infocenter/toolsctr/v1r0/index.jsp.
v Before you install optional hardware, make sure that the server is working
correctly. Start the server, and make sure that the operating system starts, if an
operating system is installed, or that a 19990305 error code is displayed,
